Abstract: A process for thermal waste treatment with the destruction or separation of hazardous components (TAZAS process - Verfahren zur thermischen $\underline{A}$bfallbehandlung unter $\underline{Z}$erstörung oder $\underline{A}$btrennung der $\underline{S}$chadstoffe) is being developed at the ResearchCentre Jülich. The actual goal of this process is to minimize all pollutants in all the various residues from the waste treatment process. This new process is characterized by the incineration of waste with concentrated oxygen at high temperatures, a recycling of filter dusts with separation of heavy metals in the incinerator, and the production of a very leach-resistant slag. Relative to waste incineration with air the off-gas quantity is reduced by incineration with oxygen to about 1/5. Furthermore, the incineration itself and subsequently pollutant separation is not impaired by the high amount of nitrogen. This results in a very low concentration of products from local, incomplete incineration (such as CO, C$_{n}$H$_{m}$ and dioxins) and the separation of hazardous products such as HCI, SO$_{2}$ and heavy metals from the off-gas is facilitated. By feeding most of the filter dust back into the furnace this dust finally enters the slag so that a landfill disposal of filter dust can be practically dispensed with. The slag from the waste incineration is removed from the furnace in a molten state and characterized by high leach resistance. The essential characteristics of the process are now being examined experimentally in a first experimental series. The experiments were carried out in a pilot plant where the waste was incinerated with concentrated O$_{2}$ in a special swing furnace.
